Abstract
According to embodiments of the invention, an in-cell capacitive contact panel and a manufacturing method thereof are provided. The in-cell capacitive touch panel comprises an array substrate. The array substrate comprises a display pixel structure and a touch circuit, and the touch circuit comprises a sensing unit and an amplifying unit connected with each other. The sensing unit is connected to a gate line in the display pixel structure. A switch-on voltage is provided by the gate line in the display pixel structure to the sensing unit, a voltage is generated in the sensing unit after the sensing unit is switched on, the voltage generated in the sensing unit is changed by a touch operation, the amplifying unit amplifies the voltage change in the sensing unit and outputs the amplified voltage change.
